Heavy metal pollution affects the cognitive health of bees

Heavy metals, such as lead and arsenic, are naturally present in soil and water. However, human activities such as mining, metallurgy and car traffic have considerably increased their concentrations, exposing human and animal populations to potentially toxic doses that are still poorly assessed.

Coline Monchanin, Erwann Drujont, Jean-Marc Devaud and Mathieu Lihoreau (CRCA-CBI) and their colleagues have published a study showing the impact of heavy metal pollution on the health of bees, which are essential to the proper functioning of ecosystems.
